you can adapt any app you make to take input from the wiimote using the wiilib so you could have a game like duck hunt or something and the trigger fires the gun if your using a wiimote. the wiimote does not have a standard driver for windows that just automatically makes it a mouse, or at least not that i know of.
Another potentially newb question:Is there any licensing, IP, or patent infringement issues here if some company decides to use this technology in a specific application? I see a license for the WiimoteLib but it doesn't appear to be restrictive.Has anyone (Johnny?) patented the idea of "using IR based technology to provide interactive surfaces"?
